Core AWS services use it too. Even if you are hosted in another region, you can still be affected by a US-East 1 outage
replyThe idea would be to actually load distribute between different cloud providers.
replyBut even then , the load balancer needs to run somewhere. Which becomes a new single point of failure.
I’m sure someone smarter than me has figured this out.
yes, they have. It just costs a shit ton of money and is extremely difficult to get the suits to sign off on TWO full 'cloud services' bills. It generally doubles your cost and workload and increases your uptime by a couple hours/year, assuming you don't have bugs that affect one or the other cloud in your deployment stack.
replyIt's basically a wash for almost all organizations for twice the cost and effort.
Ok...
replyBut where does the load balancer actually run. Does load balancer main run on AWS, and load balancer backup on Oracle?
Short TTL DNS or BGP anycast.
replyalso these things don't go down THAT often... well aws, not some others. More uptime that you probably had before. even the stock market takes a few days off every decade. Just ask W.
reply> not some others.
replyLooking at Azure and GitHub in particular. ;)
DNS
replyNot really. Your clients can random robin to connection points across providers and move write heads upon connection. If you worry about hard coding you can reduce the surface to a per-context first minimum contact point.
replyI was surprised recently when setting up cloudfront with aws certs that it forced me to use us-east-1 to provision the certs.
replySTS is only on us-east-1 I believe
replyYep. All of the identity and access management services for the non-China public cloud are in us-east-1. https://news.ycombinator.com/item?id=48071472
replyAll the control plane. Data plane is distributed and roles using iam to access resources can still do so during a control plane outage.
replyBingo. This is the one most people don't know about.
reply> It worked out with my first girlfriend. The twins are fluent in English and Korean.
replyYou were dating twins as a form of redundancy?!
